Replaced StatusServlet with a flow

[Cantor, Scott]

Partly as an exercise, and partly to get more junk out of web.xml, I
replaced the old servlet with a flow and view, which led me to notice that
I don't think the Version class from V2 is actually working properly, I
think because there's no actual jar built by idp-parent, which is where
the maven jar plugin is running.

I also seem to have broken the integration-tests project, but I'm not sure
why, it's complaining about component IDs not being set for some reason.
